Kerala Agricultural University, Thrissur

The history of agricultural education in Kerala can be traced back to the year 1896 when a scheme was evolved in the erstwhile Travancore State to train a few young men in scientific agriculture at the Demonstration Farm, Karamana, Thiruvananthapuram, presently, the Cropping Systems Research Centre under Kerala Agricultural University. Agriculture was introduced as an optional subject in the middle school classes in the State in 1922 when an Agricultural Middle School was started at Aluva, Ernakulam District. The popularity and usefulness of this school led to the starting of similar institutions at Kottarakkara and Konni in 1928 and 1931 respectively. Agriculture was later introduced as an optional subject for Intermediate Course in 1953. In 1955, the erstwhile Government of Travancore-Cochin started the Agricultural College and Research Institute at Vellayani, Thiruvananthapuram and the College of Veterinary and Animal Sciences at Mannuthy, Thrissur for imparting higher education in agricultural and veterinary sciences, respectively. These institutions were brought under the direct administrative control of the Department of Agriculture and the Department of Animal Husbandry, respectively. With the formation of Kerala State in 1956, these two colleges were affiliated to the University of Kerala. The post-graduate programmes leading to M.Sc. (Ag), M.V.Sc. and Ph.D. degrees were started in 1961, 1962 and 1965 respectively. On the recommendation of the Second National Education Commission (1964-66) headed by Dr. D.S. Kothari, the then Chairman of the University Grants Commission, one Agricultural University in each State was established. The State Agricultural Universities (SAUs) were established in India as an integral part of the National Agricultural Research System to give the much needed impetus to Agriculture Education and Research in the Country. As a result the Kerala Agricultural University (KAU) was established on 24th February 1971 by virtue of the Act 33 of 1971 and started functioning on 1st February 1972. The Kerala Agricultural University is the 15th in the series of the SAUs. In accordance with the provisions of KAU Act of 1971, the Agricultural College and Research Institute at Vellayani, and the College of Veterinary and Animal Sciences, Mannuthy, were brought under the Kerala Agricultural University. In addition, twenty one agricultural and animal husbandry research stations were also transferred to the KAU for taking up research and extension programmes on various crops, animals, birds, etc. During 2011, Kerala Agricultural University was trifurcated into Kerala Veterinary and Animal Sciences University (KVASU), Kerala University of Fisheries and Ocean Studies (KUFOS) and Kerala Agricultural University (KAU). Now the University has seven colleges (four Agriculture, one Agricultural Engineering, one Forestry, one Co-operation Banking & Management), six RARSs, seven KVKs, 15 Research Stations and 16 Research and Extension Units under the faculties of Agriculture, Agricultural Engineering and Forestry. In addition, one Academy on Climate Change Adaptation and one Institute of Agricultural Technology offering M.Sc. (Integrated) Climate Change Adaptation and Diploma in Agricultural Sciences respectively are also functioning in Kerala Agricultural University.

    Evaluation of tree species for growth, wood properties and leaf nutrient content
    (Department of Forest Management and Utilisation, College of Forestry, Vellanikkara, 2008) Harsha, T Hegde; KAU; Gopikumar, K
    The present study was conducted in the College of Forestry, Kera1a Agricultural University, Vellanikkara to evaluate the growth performance, biomass production, wood properties and leaf nutrient content of the selected tree species grown in the arboretum during the period 2006 to 2008. The species selected for the study includes Adenanthera pavonina, Artocarpus heterophyllus, Bridelia retusa, Ceiba pentandra, Hydnocarpus wightiana, Hymenodictyon excelsum, Peltophorum pterocarpum, Pterocarpus santalinus, Samadera indica and Tectona grandis. Data related to growth measurements from 1992 to 2006 have been collected from the college department. The results revealed that the species like Tectona grandis, Ceiba pentandra and Artocarpus heterophyllus were fast growing in terms of height and girth while Samadera indica as slow growing. Peltophorum pterocarpum produced highest number of branches. The spread was the maximum for Artocarpus heterophyllus followed by Adenanthera pavonina. During the end of the study in 2008, maximum volume increment was recorded by Ceiba pentandra while the lowest was for Samadera indica. The total biomass production was found to be the maximum for Ceiba pentandra in terms of fresh and Adenanthera pavonina in terms of dry weight while the lowest total biomass was produced by Pterocarpus santalinus in terms of both fresh and dry weights. Trunk accounted for maximum biomass production followed by branches. The contribution of trunk was followed by branches in all the tree species except Ceiba pentandra where the dry weight of leaves was more than that of branches. Adenanthera pavonina, Tectona grandis and Pterocarpus santalinus produced more heartwood percentage compared to other species. Sapwood percentage recorded was the maximum for Samadera indica. Pterocarpus santalinus, Hydnocarpus wightiana and Ceiba pentandra were having high calorific values and hence could be used for fuel wood purpose also. Specific gravity was found to be the maximum for Samadera indica and minimum for Pterocarpus santalinus. Leaf tissue nitrogen content was significantly highest in Adenanthera pavonina followed by Pterocarpus santalinus. The phosphorus content was found to be the maximum in Artocarpus heterophyllus while minimum in Ceiba pentandra. Leaves of Tectona grandis recorded the maximum content of potassium while the lowest was for Artocarpus heterophyllus. The present series of investigations indicate the scope of selecting fast growing tree species with high biomass production, better wood qualities and high foliage nutrient content for distribution to farmers for social/agroforestry and even for general afforestation programmes.
